This 2-7/8 EUE pin x 3-1/2 EUE box pup joint, measuring 180mm in length, is a threaded connector used to join tubing strings of different nominal sizes in oil and gas wells. Supplied by Henan Dongfanglong Machine Manufacture Co., Ltd from Puyang, Henan, China, it is manufactured to API 5CT standards. The product features an External Upset End (EUE) pin connection on one end and an EUE box connection on the other, allowing for a secure transition between 2-7/8 inch and 3-1/2 inch tubing.
Pup joints like this are critical for adjusting the length of a tubing string during well completion or workover operations. The material is specified as carbon steel in API grades such as J55 or L80, which are common for standard well conditions. Typical industry specifications for EUE connections include a tapered, round thread design with 8 threads per inch, providing a reliable metal-to-metal seal. The 180mm length is a standard short length used for precise spacing adjustments.
Drilling contractors, well service companies, and OCTG distributors source these fittings for their inventory of downhole tools. The product is used in oil extraction, water well drilling, and geothermal energy projects. Buyers should confirm the exact material grade, thread dimensions, and any required pressure testing with Henan Dongfanglong. The supplier offers trade terms such as FOB and CIF, providing flexibility for international logistics.

When sourcing this 2-7/8 x 3-1/2 EUE pup joint from Henan Dongfanglong, your first step is to confirm all technical specifications against your well schematic or equipment list. Verify the exact material grade required, the thread dimensions and gauging standards, and the 180mm length tolerance. Requesting a detailed datasheet or drawing from the supplier is advisable.
Clarify all commercial and logistics terms before placing a purchase order. Key items include the Incoterms (e.g., FOB Tianjin or CIF your port), the total landed cost, the payment terms (e.g., T/T, L/C), and the estimated shipping date. For fittings, sea freight in cartons on pallets within a container is typical. Ensure the packaging protects the threaded ends from damage during transit.
Establish a quality assurance protocol. Beyond relying on the supplier's API certification, consider specifying third-party inspection at the mill or prior to shipment. This inspection can include dimensional checks, visual examination for defects, and review of the material test reports. Having clear acceptance criteria in your purchase order protects your investment and ensures the components will perform as expected downhole.
